Line a rimmed baking sheet with non-stick foil and spray with non-stick cooking spray.
Add saltine crumbs, parmesan cheese, milk and Worcestershire Sauce to a bowl and stir to combine. Set aside.
In a food processor, add the onion, garlic and parsley and pulse until very finely minced.
In a large bowl, combine the beef, eggs, onion mixture, saltine mixture, BBQ sauce, and All Purpose seasoning. Mix until just combined.
Form into a loaf on the prepared baking sheet. Be careful not to pack it too tightly.
Bake for 40 minutes.
While the meatloaf is baking, combine the glaze ingredients in a small bowl.
Evenly coat the top of the meatloaf with the BBQ glaze and bake for an additional 15-20 minutes or until the internal temperature reaches 160 degrees F.
Let the meatloaf rest for 10 minutes before serving.
Christina's Notes
Vegetables: Add some vegetables into the glaze, like chopped green onions, carrots, or celery.
Spices: Add spices, like onion powder, garlic powder, or paprika.
Sauce: Try sweet or spicy BBQ sauce for a different flavor.
Meat: Be careful not to pack the meat too tightly or you'll end up with a very dense, tough loaf.
